Application February 8, 1941, Serial No. 378,088

1 Claim.

My invention relates to milk sediment testin device and has as one of the principal objects thereof the provision of a milk sediment testing device so constructed and arranged whereby a sample of the sediment contained in a receptacle may be readily taken from the bottom of the receptacle.

An important object of my invention is to provide a device of the character described which is simple in construction, durable in use, efficient in operation and economical in manufacture.

Other objects and advantage will be apparent from the following description, appended claim and annexed drawing.

Referring to the drawing wherein like reference characters designate like part throughout the several views:

Figure 1 is a side elevation, partly in section, of my device disposed in a milk can.

Figure 2 is a view similar to Figure 1 with the parts in a different position.

Figure 3 is a vertical sectional view of the lower end of my device.

Figure 4 is a vertical sectional View of the lower end of my device with the parts disposed in disassembled relation.

In practising my invention, as illustrated in thedrawing, I provide a tube In formed with a chamber I! in which operates a plunger l2 fixed to the lower end of a rod l3 slidably extending through a closure I4 capping the upper end of the tube and with the outer or upper end of the rod l3 provided with a finger-ring l5 for reciprocating the plunger within the chamber. The lower end of the tube has mounted therein a sleeve l6 formed on its lower end with an outwardly disposed circumferential flange I'l engaging and underlying the under face of said lower end of the tube Ill. The lower face of the flange I! has secured thereto a strainer Hi, the latter being preferably constructed of wire mesh.

Secured about the peripheral face of the lower end of the tube It! is the upper end of a collar I9, the latter being preferably constructed of resilient material, for instance, rubber. The collar 19 extends an appreciable distance subjacent the lower end of the tube and is fashioned with an inwardly disposed circumferential flange 20 constituting a seat on which is positioned a filter disk 2|, the latter being interposed between the flange 2D and strainer [8 as clearly illustrated in Figure 3. The collar, being constructed of resilient material serves to maintain the disk clamped between the strainer and seat and thereby precludes accidental displacement of said disk.

In operation, the tube It) is inserted within a milk can 22 containing milk 23 and with the lower end of the collar disposed in proximity to the bottom 2d of the can as illustrated in Figure When the parts are thus arranged, the plunger is drawn upwardly by the rod l3 and todraw milk into the chamber II from the bottom of the can. Due to the lower end of the collar being disposed in proximity to the bottom of the can, sediment from the bottom of the can is drawn into the collar with the milk and deposited on the disk. When a sample of the sediment is thus obtained, the collar is removed from the tube to permit removal of the disk in order that the sediment collected thereon may be subjected to a suitable analysis or study. 7

From the foregoing, it will be apparent that my invention permits of samples of sediment to be taken from producers cans before emptying and that the device may be readily operated without skilled labor.

Without further elaboration the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and that the invention comprehends all construction within the scope of the appended claim.

What I claim is:

A device of the character described, comprising, a tube adapted to be inserted into a, receptacle containing liquid having sediment accumulated on the bottom of said receptacle, said tube having a lower end and provided with means for withdrawing liquid from said receptacle into said tube through said lower end, a sleeve carried by said lower end and provided with a strainer, a filter disk disposed subjacent said strainer and adapted to be positioned in proximity to the bottom of said receptacle for accumulating sediment during drawing of liquid into said tube, and means carried by said tube and detachably connected to said disk for holding the latter against the bottom of the strainer and thereby maintaining it in proximity to the bottom of said receptacle.

OSCAR HANSON.
